80 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Use when capturing or analyzing ETTrace profiles for a focused iOS launch or runtime flow, including exact-build dSYM UUID matching, Simulator or device capture, processed per-thread flamegraph JSON, sampled inclusive/exclusive time, unresolved symbols, and comparable verification. Use debugging-instruments or swiftui-performance for generic profiling instead.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'ios-ettrace-performance' ] || [ -L ~/.agents/skills/'ios-ettrace-performance' ]; then echo 'A skill folder named ios-ettrace-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dpearson2699/swift-ios-skills' "$d" && git -C "$d" checkout --quiet '8d90fd121a263355a4fb44fd082af1416a5c1c2a' -- 'skills/ios-ettrace-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/ios-ettrace-performance' ~/.agents/skills/'ios-ettrace-performance' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'ios-ettrace-performance' ~/.claude/skills/'ios-ettrace-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
